[golang] Libuplink Slow?

I’ve noticed that upload and delete operations are pretty slow. Is this expected? I ran 100 adds and 100 deletes to come up with this:

|Std Dev|0.797315975|0.360070539|

Those .4 second uploads are nice but up to 4 seconds with an average of 2?! My upload and delete functions are pretty much just as presented in the Walkthrough and during this time period my latency to the satellite is pretty good:

--- us-central-1.tardigrade.io ping statistics ---
384 packets transmitted, 384 received, 0% packet loss, time 383465ms
rtt min/avg/max/mdev = 18.865/19.956/39.493/1.482 ms

Is there something I can be doing to make uploads faster?
